>From BitcoinJ bloomfilter side you have the issues resolved  if you use a loca node. In Bisq all network traffic goes over tor (only exception is in-app download but you dont need to use that).
The main issue remaining is to not link together all your trade on the blockchain by using outputs of one trade as input for the next. This is not as trivial to achieve if you dont seperate each trade at funding and withdrawing at the end.
So if you fund a bisq trade from external wallet with untainted coins (e.g. out of wasabi) and then when trade comleted to send it out again to wasabi or a separated wallet your trades are not connected on the blockchain. 
But it is all relative, even if your trades get connected one can derive that one entity has traded x times on Bisq but does not know the identity as long you are not trading fiat where the peer will see your payment method data and thus get some link to your real life ID. But that is only visible to the peer. If you trade altcoins it depends on your behaviour on the altcoin chain as well how much the altcoin provides privacy. XMR is clearly the best in that regards.

Privacy is not a binary thing, and things get quickly pretty complex....
